Abstract
Systems and methods for downhole completions. A downhole running tool can have a body having a bore formed therethrough. A latch member can be disposed on a first portion of the body. A reset member can be disposed on a second portion of the body. A conduit can be formed within a sidewall of the body. The conduit can be located between the first and second portions of the body. A pressure relief port can be disposed at a first end of the conduit; and a first flow port can be disposed at a second end of the conduit. The pressure relief port and first flow port can be in communication with an outer diameter of the body.
Claims
exact text as granted — not AI-modified1. A completion system comprising:
a first assembly comprising:
a body having a bore formed therethrough;
a latch member disposed on a first portion of the body;
a reset member disposed on a second portion of the body;
a first conduit formed within a sidewall of the body, the first conduit located between the first and second portion of the body;
a pressure relief port disposed at a first end of the first conduit; and
a first flow port disposed at a second end of the first conduit, wherein the pressure relief port and a first flow port are in communication with an outer diameter of the body and are sealed off from the bore within the body; and
a second assembly comprising:
a housing with a bore formed therethrough, wherein the first assembly is disposed at least partially within the bore of the housing;
a first portion of the housing engaged with the latch member; a second flow port formed into the housing and sealed off from the exterior diameter of the housing, wherein the second flow port is engaged with the first flow port;
a second conduit formed within a sidewall of the housing and in communication with the second flow port; and
a protection mechanism disposed within a second portion of the bore of the housing and engaged with the reset member, wherein:
the protection mechanism has a stroke limited between a first position and a second position, and wherein the protection mechanism covers the second flow port when the protection mechanism is in the second position.
2. The system of claim 1 , wherein the first assembly and first flow port form a seal between the second conduit and the bore of the housing.
3. The system of claim 1 , wherein the reset member is connected to the second portion of the body of the first assembly.
4. The system of claim 1 , wherein the latch member comprises:
at least one sleeve; and
a collet, wherein the at least one sleeve is disposed about an outer surface of the body and adapted to axially move about the outer surface of the body; and wherein
at least a portion of the collet is disposed about an outer diameter of the at least one sleeve.
5. The system of claim 1 , wherein the reset member comprises a collet disposed adjacent a second portion of the body, wherein the collet comprises one or more collapsible fingers adapted to engage an inner diameter of the protection mechanism.
6. The system of claim 1 , further comprising at least one sealing element disposed about the body adjacent at least a portion of the first conduit.
7. A method for running-in a downhole completion comprising:
locating the completion system downhole; wherein the completion system comprises:
a first assembly comprising:
a body having a bore formed therethrough;
a latch member disposed on a first portion of the body;
a reset member disposed on a second portion of the body;
a conduit formed within a sidewall of the body, the conduit located between the first and second portion of the body;
a pressure relief port disposed at a first end of the conduit; and
a first flow port disposed at a second end of the conduit, wherein the pressure relief port and a first flow port are in communication with an outer diameter of the body and are sealed off from the bore within the body; and
a second assembly comprising:
a housing with a bore formed therethrough, wherein the first assembly is disposed at least partially within the bore of the housing;
a first portion of the housing engaged with the latch member;
a second flow port formed into the housing and sealed off from the exterior diameter of the housing, wherein the second flow port is engaged with the first flow port;
a second conduit formed within a sidewall of the housing and in communication with the second flow port; and
a protection mechanism disposed within a second portion of the bore of the housing and engaged with the reset member; and
the method further comprising:
protecting the second conduit within the second assembly from pressure buildup and external fluid as the completion system is located downhole;
actuating the second assembly;
releasing the first assembly from the second assembly;
removing the first assembly from the second assembly; and
protecting the second flow port with the protection mechanism after the first assembly is removed.
8. The method of claim 7 , wherein releasing the tool comprises applying pressure to a wellbore annulus formed between the first assembly and a wall of the wellbore or applying pressure to the bore of the body of the first assembly.
9. The method of claim 7 , wherein releasing the first assembly comprises rotating the first assembly.
10. The method of claim 7 , wherein protecting the second conduit from pressure build up further comprises compensating for pressure drop.
11. The method of claim 7 , further comprising preventing the first assembly from rotating out of the second assembly while running the completion system downhole.
12. The method of claim 7 , wherein protecting the second flow port formed into the second assembly after the first assembly is removed comprises moving the protection mechanism to a second position, wherein when the protection mechanism is in the second position the protection mechanism at least partially covers the second flow port, and wherein when the protection is in the second position the protection mechanism protects the second flow port from external fluid or debris.Cited by (0)
